摘要 目的:观察缺氧复氧后肾小管上皮细胞细胞间黏附分子1(ICAM-1)的表达及胡黄连提取物对其的影响。方法:建立人肾小管上皮细胞缺氧复氧损伤模型,分别用不同浓度胡黄连提取物(10μg/ml、100μg/ml、1000μg/ml)进行预干预,采用流式细胞术不同组细胞内氧化应激水平,流式细胞术检测细胞ICAM-1蛋白表达,RT-PCR法测定细胞ICAM-1mRNA表达。结果:正常情况下肾小管上皮细胞氧化应激水平极低,缺氧复氧后肾小管上皮细胞内氧化应激水平明显升高,细胞ICAM-1蛋白和mRNA表达上调,且随缺氧时间的延长,细胞内氧化应激水平逐渐升高(P<0.05),ICAM-1表达逐渐增强(P<0.05);胡黄连提取物呈剂量关系抑制细胞内氧化应激水平(P<0.05),同时呈剂量关系抑制ICAM-1表达的上调(P<0.05)。结论:缺氧复氧导致肾小管上皮细胞内氧化应激增强,进而诱导ICAM-1表达上调;胡黄连提取物可以通过抑制细胞内氧化应激抑制ICAM-1的上调。
